LUIGI ANGIULLI, OF NEW YORK, N. Y.

SIGNAL APPARATUS.

Application filed April 15, 1918.

To all whom it may concern Be it known that I, LUIGI ANGIULLI, re-

siding at the city of New York, borough of Manhattan, in the county and State of New York, have invented certain new. and useful Improvements in Signal Apparatus,

- of which the following is a full, clear, and

7 so constructed and arranged as to be readily assembled.

Further, said invention has for its object to provide a signal apparatus comprising a shell, a diaphragm and diaphragm actuating means rotatably mounted upon a member fixedly supported upon the shell.

Further, said invention has for its object to provide a signal apparatus comprising a diaphragm, a two-part shell havlng a tierod to hold the parts assembled, and diaphragm actuating means rotatably mounted uponthe tie-rod. r I,

Further, said lnventlon has tor its object to provide asignalapparatus casing comprising a shell consisting of a plurality of parts suitably maintained in assembled position, and a resonator carried by the shell.

Otherobjects will in part be obvious and in part be pointed out hereinafter.-

. To the attainment of the aforesaidobjects and ends my invention conslsts in the novel ,details of construction, and inthe combination, connection and arrangement of parts hereinaftermore dully described andthen pointed out in the claims, f f

In the accompanying drawing showing an illustrative embodiment of the invention g Figure l is a plan view of .a signal apparatus constructed according-to and emboclying the invention;

Specification of Letters Patent.

Patented Dec. 2, 1919. Serial No. 228,595.

Fig. 3 is a sectional View taken substantially on the line 33 of Fig. 2, and

Fig. 4 is a sectional view takensubstantially on the line4-4 of Fig. 2.

Referring to the drawing 10 indicates V a shell consisting of two parts 11 and 12 held in assembled relation by a tie member comprising a tie-rod 13, having threaded ends extending through perforations formed .in the side walls of the shell parts 11 and 12 and carrying nuts 14. The inner edge of the part 11 is offset slightly, as. indicated at 15, to form a recess to receive the inner edge ofthe part 12 whereby a close fitting joint is provided in order to prevent dirt or moisture from entering the shell. The side walls of the shell parts 11 and 12, which are substantially parallel to one another throughout the greater portion of the shell, are flared outwardly at their front portions, as indicated at 15, to form a circular opening for the shell, and are provided with .inwardly extending arc-shaped flanges 16 to which an annular plate 17 is secured by bolts 18. 19 indicates a resonator provided at its rear end with an outwardly-extending flange 2O registering with the annular plate Clamped between the annular plate 17 and theflange 20 of the resonator 19, is a dia- .phragm 22, preferably formed of sheet metal, provided at its center with a threaded bushing 23 within which is adjustably mounted a wear'member 24, con- 1 sisting of a threaded pin having its inner end beveled or pointed. The wear member is held in its adjusted position by means 1 of a locknut 25 threaded upon its outer end.

Rotatably mounted. upon the tie-rod 13 is a diaphragm actuator, which is shown as comprising a fly wheel 26 and a disk 27 provided with peripheral teeth 28 adapted to engage the inner end of the wear member 24. A spring-pressed pawl 29, carried by the diaphragm actuator26, 27 engages the teeth of a pinion 30 rotatably supported 7 upon the tie-rod 13. This construction insures the rotation "of the diaphragm actuator 26, 27, when the pinion '30 is rotated in one direction, and permits the pinion to rotate in the opposite direction without rotating the diaphragm actuator. In order to mainpain the pinion 30 and the dlaphragm actuator 26, 27 properly positioned upon the tie-rod 13' and to protect the walls of the shell against wear, a washer is positioned upon the tie-rod 13 between "the pinion and the wall of the shell part 11, and a bushing 32 is positioned upon the tie-rod 13 between 1211? diaphragm actuator 26, 27 and the WELll Of the shellpart 12.

A guide member 33, carriedby the shell 10, has its lower end secured thereto a d]a- "cent thebottom thereof and has its ripper end projecting through the top wall of the shell 10. Reciprocatingly mounted within the guide member 33 is a plunger pro- Vided with plurality of teeth 35 constituting a rack" and engaging" the pinion 30. The plunger 34 is" normally maintained raised by means of a spring '36 having one ofitsendsiastened to bracket secured t t h 10 and hav n t e her aging a stop 3 carriedby'the plunger 34;.

ec ed a he ppe e d' the Pl 4 i hle d 38 ad e e be en ed y the hand in order todepress the plunger 34"whn thehorn is to be operated. As shown, the head 38 rests upon the upper end or the plunger 34 and is held in place thereon by an upwardly extending reduced portion 39 which extends through a correofth'e springpressed pawl 29'with the pin-e ion 30. *"Asthe diaphragnractuator 26, 27 rotates the teeth 28' on the eriphery 9f the disk 27 will su cessively engagethe inner end .of the wear member 24; carried" by the diaphragm 22 thereby causing the diaphragm 22 tovibrate and produce an audible signer-Upon remo ing the pressure of 'thehand fromthe head 87 of the plunger 3i, afterit has been depressed to its lowerplunger are) its normahposition. i During this upward ovement of theplunjger 34:

the pinion 30Wlll be rotatedin the-opposite or reverse direction to that in which it was rotated by the depression of the pluii'ger 34:, but the rotation of the pinion 30 in such reverse direction will have no effect on the rotation of the diaphragm acwill'cont'inue to rotate during the time that assess i was er-a W l i tuator26,27,asthe spring pressed pawl 29 will ride over the teeth of the pinion 30. The

diaphragm'actuator 26, 27, is'there'fore free to'rotate'upon'the tle rod 13, and, by reason of the momentum of the fly wheel 26, it

mally raised position by the spring 36. It

will thus be understood that by quickly and s ocess yely depressing the plunger 3tand allowing it to return to its normal position a number of times, a continuous signal can be produced.

Ewing thus described my said nvention what I claim and desire tosecure by Letters Patent is 1. In a signal apparatus, in combination, a shell comprising a plurality of parts, means fofholding saidparts in assembled position, a sound producing element opera tively associated with said shell, means for actuating said sound producing element sup ported upon said holding-means, and means for operating said actuating means, substantially as specified.
